CVE-2026-98723

The Linux kernel contains a vulnerability in the nvmet subsystem where the hostid is incorrectly copied into the controller. Due to a sequence error in the nvmet_alloc_ctrl() implementation, nvmet_ctrl_init_pr() snapshots a nil UUID into per-controller per-namespace reservation references because...

CVE-2026-98722 mtd: block2mtd: Fix divide error when erase_size is zero

In the Linux kernel, the following vulnerability has been resolved: mtd: block2mtd: Fix divide error when erasesize is zero The erase size is parsed from the "block2mtd" module parameter and can be set to zero. adddevice then evaluates if size % erasesize with a zero divisor, which triggers a...

CVE-2026-98722

The Linux kernel contains a vulnerability in the mtd: block2mtd module where a divide error occurs if the erase_size module parameter is set to zero. The add_device() function performs a modulo operation (size % erase_size) without first validating that erase_size is non-zero, leading to a kernel...

CVE-2026-98721 mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ The Cadence NAND interrupt handler uses both the IRQ lock and completion object. Registering the IRQ before initializing them leaves a window in which a pending...

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ The Cadence NAND interrupt handler uses both the IRQ lock and completion object. Registering the IRQ before initializing them leaves a window in which a pending...

CVE-2026-98721

The Linux kernel contains a vulnerability in the mtd: rawnand: cadence driver. The issue arises because the Cadence NAND interrupt handler uses both an IRQ lock and a completion object , but these are registered before being properly initialized. This sequence creates a race condition where a pen...

CVE-2026-98719

The Linux kernel contains a vulnerability within the KVM SEV component related to memory management. Specifically, the have_run_cpus mask pointer is not consistently nullified when freed, particularly during error paths in ** oo_sev_guest_init()**. This oversight can lead to a double-free conditi...
